Papa Roach pulls out of Rockstar Energy Drink Uproar Festival

Papa Roach has withdrawn from the remaining Rockstar Energy Drink Uproar Music Festival tour dates so frontman Jacoby Shaddix can deal with a nodule found on his left vocal cord.

Doctors have suggested Shaddix take a break from singing to undergo corrective surgery to remove the nodule and prevent further damage, according to a press release.

"It's no secret that I've been having issues with my voice lately," Shaddix explained in the press release. "I was hoping to be able to go out there and kill it on this tour by resting and doing vocal exercises, but my voice has just gone out on me. I hate to let our fans down, but unfortunately surgery is the only way to fix it. The last thing we want to do is give our fans less than 100 percent every night. We know they'll understand and we'll be back better than ever."

As of Friday (8/24), the Uproar fest's main stage schedule was adjusted for Papa Roach's absences with longer performances by Shinedown, Godsmack, Staind and Adelitas Way.

The festival also includes P.O.D., Deuce, Fozzy, Redlight King, Mindset Evolution, In This Moment, Thousand Foot Krutch, Candlelight Red and a local Battle of the Bands winner on the Ernie Ball Stage and the Jagermeister Stage. More information about the festival is available at the event's website.
